Abstract
The invention discloses a cutter bar of a novel boring cutter, and belongs to the field of metal cutting cutters. The cutter bar of the existing boring cutter can not be suitable for different cutter blades. The cutter bar of the novel boring cutter provided by the invention comprises a cutter bar base body, a cutter blade holder and a fastening bolt, wherein the cutter bar base body is provided with a concave conical hole; the cutter blade holder is provided with a convex conical body; small ends of the convex conical body and the concave conical body are in interference fit; the convex conical body is provided with an axial thread hole; the cutter bar base body is provided with a step through hole which is communicated with the concave conical hole; and the fastening bolt penetrates through the step through hole and is screwed into the thread hole in the convex conical body. A cutter bar base body can be correspondingly matched with multiple kinds of cutter blade holders, and the corresponding match of the cutter bar base body with multiple kinds of cutter blades is realized; and high connecting accuracy and connecting rigidity can be met.
Description
Technical field
The invention belongs to the metal cutting tool field, especially relevant with a kind of split type novel boring bar.
Background technology
Existing boring cutter generally comprises blade, knife bar, and blade bearing is set on the knife bar, changes blade behind the blade abrasion and gets final product, and need not more changing knife rod.Different processing mode such as heavy boring, right boring needs different blades; Blade difference then blade bearing is also different, and existing boring cutter can only be realized identical blade exchange, changes different blades if desired; Just need more changing knife rod, still exist knife bar can't adapt to the defective of different blades.
Summary of the invention
The object of the invention is exactly to solve the defective that existing boring bar can't adapt to different blades, and a kind of boring bar that can mate different blades is provided.For this reason, the present invention adopts following technical scheme:
Novel boring bar; It is characterized in that: described knife bar comprises knife bar matrix, blade bearing and fastening bolt, and the concave cone hole is set on the knife bar matrix, and convex cone is set on the blade bearing; Convex cone and concave cone hole small end interference fit; Axial screw is set on the convex cone, step through-hole is set on the knife bar matrix is communicated with described concave cone hole, fastening bolt passes step through-hole and is screwed into the screw on the convex cone.Like this, a knife bar matrix just can correspondingly mate multiple blade bearing, and the corresponding coupling with blade of blade bearing has also just realized the corresponding coupling with multiple blade of a knife bar matrix; Knife bar matrix and blade bearing adopt convex cone and concave cone hole to be connected simultaneously, make both can satisfy high precision and the coupling stiffness of connecting.
Use the present invention can reach following beneficial effect: the present invention forms split type boring bar through be connected knife bar matrix and blade bearing of convex cone and concave cone hole is set; Realize the corresponding coupling of a kind of knife bar different blades, and had high precision and the coupling stiffness of connecting.
Description of drawings
Fig. 1 is the structural representation of the loose state of the present invention.
Fig. 2 is the structural representation of compact state of the present invention.
The specific embodiment
Be described in detail below in conjunction with the accompanying drawing specific embodiments of the invention.
Like Fig. 1, shown in Figure 2; The present invention includes knife bar matrix 1, blade bearing 3 and fastening bolt 2, concave cone hole 5 is set on the knife bar matrix 1, convex cone 4 is set on the blade bearing 3; Convex cone 4 and concave cone hole 5 small end interference fit; Axial screw is set on the convex cone 4, the step through-hole that is communicated with concave cone hole 5 is set on the knife bar matrix 1, fastening bolt 2 passes step through-hole and is screwed into the screw on the convex cone.As long as turn fastening bolt 2 just can load and unload blade bearing 3, when blade bearing 3 and knife bar matrix 1 end face reclined, knife bar was in compact state, through convex cone and concave cone hole be connected and end face joins, make knife bar can satisfy height connection precision and coupling stiffness.
